33.4.11.7 Block Blank Check Command
This command is used to confirm that all addresses in any block are blank data FFh.
When 25h is written in the first bus cycle and D0h is written in the second bus cycle to any block address, blank
checking starts in the specified block. The FST7 bit in the FST register can be used to confirm whether blank
checking has completed. The FST7 bit is set to 0 during the blank-check period and set to 1 when blank
checking completes.
After blank checking has completed, the blank-check result can be confirmed by the FST5 bit in the FST
register. (Refer to 33.4.12 Full Status Check.).
Do not execute the block blank check command when the FST6 bit is set to 1 (during erase-suspend).
Figure 33.14 shows the Block Blank Check Flowchart.
